{"product_id":"presser-foot-regulator-zig-zag","title":"Presser Foot Regulator Zig Zag","description":"\u003cp\u003e\u003cspan\u003eThe pressure foot regulator for the 20U43 zigzag machine consists of a threaded thumb screw and a matching knurled lock nut, typically finished in a black oxide coating for durability and grip. The main body of the regulator is a hollowed, cylindrical bolt featuring a wide, knurled head at the top for easy manual adjustment. Below the head, the shaft is fully threaded to interface with the machine's head casting, allowing it to exert downward force on the internal presser bar spring. A secondary knurled ring, the lock nut, sits on these threads to provide a tension-lock once the desired pressure is set, preventing the screw from vibrating loose during high-speed zigzag stitching. By rotating the regulator clockwise, the screw descends further into the machine, compressing the internal spring and increasing the \"bite\" on the fabric essential for heavy materials while counter-clockwise adjustments lighten the pressure to prevent delicate fabrics from puckering or \"bruising\" under the foot.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCall\/WhatsApp\u003cspan\u003e \u003c\/span\u003e\u003cspan style=\"text-decoration: underline;\"\u003e064 640 3845\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eor Email us at\u003cspan\u003e \u003c\/span\u003e\u003cspan style=\"text-decoration: underline;\"\u003efabrics@mhcworld.co.za\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003efor assistance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"color: #ff2a00;\"\u003ePRICE PER EACH\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"MHC World","offers":[{"title":"Default Title","offer_id":43035640692825,"sku":"HA229799","price":79.95,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0052\/0935\/8425\/files\/mhc-world-presser-foot-regulator-zig-zag-presser-foot-regulator-zig-zag-1220196567.jpg?v=1778488107","url":"https:\/\/www.mhcworld.co.za\/products\/presser-foot-regulator-zig-zag","provider":"MHC World","version":"1.0","type":"link"}
